Running this test under the disagg hook gives a crash:

Note: this ticket is primarily concerned with understanding and fixing the abort/crash. That alone may not fix the test, and it's okay to defer and regular logic failures to another ticket. However, if the fix allows the test to pass, please remove the test/tests from the test/hook_disagg.fail list so they will be tested regularly in Evergreen.
If an illegal flag combination appears due to programmer error, WT should return an error code, not assert.
